Die casting is a manufacturing process that uses high pressures to force molten metal from a crucible into a metal jacket. The material is then injected through a rod into a preformed mold (die). Once injected, the part is cooled, solidified and removed from the mold. This process is used for both parts and ingots.
The manufactured parts are characterized by high uniformity, good surface finish and high dimensional accuracy. The dimensions of the parts vary depending on the specifications. Weights range from a few grams for the smallest parts to several tons. We can even obtain extremely thin-walled parts. In fact, most of the parts do not need the final machining process or need very light machining.
Types of die casting
The two main types of die casting are:
The hot chamber process: The injection system is immersed within the molten metal in the crucible, which in turn is an integral part of the machine.
The cold chamber process: The material is fed from an external crucible to the injection sleeve, where a hydraulically operated plunger pushes the metal into the mold.
Within these 2 categories we have some variations: Die Casting, Vacuum Die Casting and Press Casting.
we are professionals in a wide range of casting products, besides having the versatility to obtain parts of products under drawing.
We have the support of factories equipped with all the necessary tools to obtain the desired product at the best price. Starting with the melting of material, injection, solidification and expulsion of the finished part. We also guarantee that the necessary post-treatments are carried out on the parts.
Advantages
High efficiency. Die casting machinery has a high productivity compared to other processes.
The alloys used in die casting have a long service life, easy to machine and automate.
Final quality. The dimensional accuracy of the casting is high, generally equivalent to 6 ~ 7, even up to 4.
Good surface finish, which means that further finishing will not be necessary; lowering prices per part.
High strength and hardness, generally higher than sand casting by 25 ~ 30%, but extended, the rate is reduced by about 70%.
This process allows complex thin-walled castings. For example, current zinc alloy castings have a minimum wall thickness of 0.3 mm; aluminum alloy castings up to 0.5 mm; the minimum casting hole diameter is 0.7 mm, and the minimum pitch is 0.75 mm.
Excellent dimensional accuracy (dependent on casting material, but typically 0.1 mm for the first 2.5 cm (0.005 in. for the first inch) and 0.02 mm for each additional centimeter (0.002 in. for each additional inch).
Smooth cast surfaces (1—2.5 μm (40—100 μin.) rms).
Thinner walls can be cast as compared to sand and permanent mold casting (approximately 0.75 mm (0.030 in.).
Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces).
Reduces or eliminates secondary machining operations.
Rapid production rates.
Casting tensile strength as high as 415 MPa (60 ksi).
Disadvantages
The main disadvantage of die casting is its high cost. Both the necessary casting equipment and the dies and related components are very expensive compared to most other casting processes.
The process is limited to high-flow metals. Fluidity failures can lead to increased scrap rates, and scrap costs in die casting are high.
Die casting involves a large number of parts, so repeatability issues are especially important.
Die casting weights have previously been limited to between 30 grams (1 oz) and 10 kg (20 lb), but as of 2018, parts up to 80 kilograms have become possible.
In the standard die casting process, the final part will have a small amount of porosity. This prevents any heat treatment or welding, because the heat causes the gas in the pores to expand, leading to micro-cracks inside the part and surface exfoliation. However, some companies have found ways to reduce the porosity of the part, which allows welding and heat treatment to be limited.
Casting weight must be between 30 grams (1 oz) and 10 kg (20 lb). Casting must be smaller than 600 mm (24 in.). High initial cost. Limited to high-fluidity metals.
A certain amount of porosity is common. Thickest section should be less than 13 mm (0.5 in.). A large production volume is needed to make this an economical alternative to other processes.
5 Advantages of Die Casting Technology
1. Complex Thin-walled Parts
Aluminun die casting can manufacture complex-shaped and light components but with an excellent strength-to-weight ratio, giving it an edge over other metal molding castings and investment castings. Die casting parts with aluminum alloys can have a thickness as low as 0.5mm; the wall thickness of cast parts made with zinc can even be as low as 0.3mm.
2. High Mechanical Properties
Die casting products feature excellent mechanical properties. As the liquid metal solidifies under high pressure, the product appears to be fine, compact, and crystalline. Die casting parts are rigid with high hardness and strength. Also, they have improved durability and high conductivity.
3. High Dimensional Tolerance
Die casting produces parts with high durability and dimensional accuracy. Even when exposed to harsh conditions, the parts maintain their dimensional accuracy over time. As a result, die casting is used in fabricating complex and internal parts of machines that require high standards of precision and accuracy.
Die casting maintains tighter tolerances over other casting processes. That is, parts are produced with minimal variations. The typical tolerance class of die castings is IT13~IT15 in GB/T 1800-2009. Higher precision can reach IT10~W 11. Therefore, the excellent dimensional accuracy of die casting avoids the need for machining and improves the utilization of the alloy.
4. Smooth Surfaces
Die casting parts have a smooth, consistent crystalline surface. Die casting process alloys molten metal alloy to fill up the dies and create the exact shape. Therefore, provided the die is well shaped and the process is in the right condition, the parts will be fine and smooth.
Because of making glossy parts, there is less need to proceed with additional post-processing operations, except for custom needs. What’s more, after die casting is done, products can be shipped off for delivery. This can reduce the total cycle production time.
5. Cost-Effective for Mass Production
Since the surface of die castings is often smooth with excellent mechanical features, die-cast parts often require less machining. In some cases, no machining at all. As a result, there is less need to spend on secondary operations. The ability of die casting to reduce post-processing costs helps ensure its cost-effectiveness.
Notably, die casting machines, molds, and other related types of equipment are quite expensive. However, mass production aids in better distribution of cost through the production process, thereby making the die casting process economical.
5 Disadvantages of Die Casting Technology
1. Easily Generate Porosity
In the die casting process, molten metal rapidly fills the mold cavity at high speed, but the cavities lack gas permeability. Hence, gas bubbles that affect the structural integrity of fabricated parts tend to get trapped within castings.
The presence of gas cavities in die castings would affect such parts when exposed to harsh conditions, such as hardening by heat treatment. Additionally, such parts are predisposed to machining difficulties. Therefore, the machining allowance of the parts should be kept minimal. If not, the hardened layer on die casting surfaces would be removed, thereby exposing the surface.
2. Usually Support Non-ferrous Metals Only
Generally, die casting is perfect for non-ferrous metals with lower melting points than ferrous metal alloys. However, the process supports ferrous alloys like iron and steel. Ferrous metals have very high melting points and low corrosion resistance, which causes low die life. Therefore, manufacturers always choose non-ferrous metal alloys for die casting.
Moreover, casting ferrous metals come with lots of complexity and several unforeseen complications. Consequently, manufacturers stick to non-ferrous metals only for die casting operations.
3. Not Suitable for Low Volume Production
Die casting is not a practical choice for low volume production, because the tooling cost of die casting machines and maintenance are quite expensive. Therefore, the process is costly and seems complex for small-scale production.
However, large-scale production becomes cost-effective as costs are well distributed over the many items produced. Suppliers don’t recommend die casting services for low-scale projects, as the process appears to be more expensive than other production methods.
4. Low Die Life
High melting point metals and alloys compromise the effectiveness of steel dies. These metals, like copper, have extensive requirements to resist thermal deformation. The continued presence of alloys with high melting points strains the molding die, thereby reducing its durability.
5. Large Capital Investment
Unlike other casting processes, the casting machine, the dies, and other related equipment for die casting are costly. Without the essential equipment, it is impossible to carry out die casting. Although cheap materials like zinc are used to cut costs, the overall production process is still expensive. The only time die casting becomes cost-effective is in large volume production.
The die casting process involves pushing or pouring molten material into a metal mold called a die. It is an excellent option for manufacturing products with high dimensional stability.
Here are some details on how die casting works, the best metals for the process, as well as its main advantages and disadvantages.
How Die Casting Works: Step-by-Step
Mold Creation: The First Crucial Step
The first step in the die casting process is creating the mold. The die or mold has an internal cavity or core that matches the shape of your desired final product.
You can use CNC machining to create high-quality molds. In modern manufacturing, mold engineers rely on Computer-Aided Design (CAD) to develop digital models of the die and Computer-Aided Manufacturing (CAM) to create the final physical product.
These programs help simulate the finest details of the mold, such as:
Temperature distribution
Heat dissipation rate
Flow rates
Lubrication efficiency
Internal friction
After passing several simulations, the mold designer shares the mold specs and drawings with specialist toolmakers. These toolmakers then run trials and use CNC machining to ensure the final mold meets your project requirements. Apart from the cavity, industrial dies may also contain:
Cooling systems
Ejector pins
Channels for metal flow
High-Pressure Injection: Speed and Precision
In this step, the molten material is injected into the die under high pressure, ensuring even distribution. You fill the mold cavity with molten metal under immense pressure, ranging from 1,400 psi to 26,000 psi.
This injection method is faster than gravity die casting, resulting in a more efficient filling rate. It allows you to develop intricate molds with thin walls and smoother surface finishes.
Cooling and Solidification: What Happens Next?
The cooling stage begins once the molten material fills the molds. Maintaining a controlled and uniform cooling rate achieves the desired microstructure. However, the molten metal needs sufficient time to solidify to prevent internal and surface defects.
Ejection and Finishing: Final Touches
Once the casting is complete, you can unclamp the mold from the casting. Depending on the presence of surface defects and your desired outcome, you then subject the ejected part to secondary finishing processes such as:
Applying coatings to enhance appearance and corrosion resistance.
Polishing to achieve a smooth surface.
Trimming excess material resulting from flashing.
Best Metals for Die Casting
The die-casting process primarily uses non-ferrous alloys including:
Aluminum is an excellent option for creating lightweight parts without compromising strength. It offers superior heat and corrosion resistance while providing more finishing options. Despite being slightly pricier than other metals, its durability contributes to an extended lifespan, making it an appealing long-term investment. Aluminum is also easy to cast and has optimal thermal and electrical conductivity properties. These characteristics make aluminum ideal for casting industrial components, tech products, and energy management systems.
Zinc is a highly customizable material and it is perfect for projects emphasizing aesthetic appeal. You can paint or plate the final product depending on your needs, as it offers a smooth surface to work with. Zinc also has a low melting point, requiring less energy for casting while enabling the mold to last longer.
Magnesium is one of the lightest materials you can die cast, offering an excellent strength-to-weight ratio. Unlike other metals, it offers excellent fluidity and is less susceptible to hydrogen porosity. Magnesium also shields against electromagnetic and radiofrequency interference, making it ideal for producing electrical housings and connectors.
Pros and Cons of Die Casting
Some key advantages of die casting over sand casting include:
Modern Technology: Die casting incorporates the latest technology, such as CAD software, CNC machining, and 3D simulation, making it highly compatible with automation.
Smooth Finish: The process delivers one of the smoothest surface finishes compared to other casting processes. If you want a specific texture or high-quality polish, you can still utilize finishing operations like sandblasting, grinding, and powder coating.
Detailed Features: Die casting enables the rapid production of complex shapes while maintaining tight tolerances. The high-pressure process can effectively push the molten material through the narrowest channels to achieve your desired outcome.
However, this manufacturing method also has some drawbacks:
The high initial investment makes low-volume production less cost-effective.
The generation of turbulence during high-pressure injection of the liquid metal may cause defects such as porosity.
There are limitations to small and medium-sized applications.
Casting is a popular modern metal manufacturing method that involves molten material and a mold. Die casting and sand casting are two of the most renowned variants of the casting process. Here’s an extensive guide to die casting vs sand casting to help you choose the best method for your next project.
Cost Comparison: Die casting has higher upfront tooling costs but is more economical for high-volume runs, while sand casting is budget-friendly for low-volume projects.
Surface Finish: Die casting produces smoother, more precise parts; sand casting often requires extra finishing due to rougher surfaces.
Production Speed: Die casting supports rapid, automated cycles for large batches, while sand casting is slower but more flexible for custom or prototype runs.
Material Options: Sand casting works with a wider range of metals, including ferrous alloys, while die casting is limited mainly to non-ferrous alloys like aluminum, zinc, and magnesium.
Durability & Strength: Die-cast parts are denser and stronger, whereas sand-cast parts can be larger and are easier to repair.
Environmental Impact: Die casting minimizes waste but uses more energy, while sand casting generates more material waste and emissions.
Die cast parts are most commonly made for use in automotive and decorative hardware applications. The process can be used to create a wide variety of parts and products, from engine components to toys. Die casting is also used in the production of many common household items, such as door-knobs and faucets.
Advantages Of Die Casting
Lower Cost Per Part: With die casting, the more parts produced, the lower the cost per part.
Accurate and Repeatable: The die cast moulds hold up to multiple uses and consistently deliver the same accuracy.
Good For Larger and More Complex Parts: The process can produce complex-shaped parts within closer tolerances than many other mass production processes.
Disadvantages Of Die Casting
Porosity: If the molten metal cools down too quickly in the mould, it is likely to develop a porous structure.
High Initial Investment: The cost of starting a die casting project is high.
Not Suitable For One-Offs: The fact that we have to make a custom die mould for each new casting project makes this method unsuitable for one-off productions.
Advantages Of Die Casting
Because die casting is a pressurized molten metal, it can produce super smooth surface on the casting. When the molten metal is forced into the cavity, it fills completely to ensure a smooth surface. Another advantage of die casting is that it can minimize the demand of finishing process. Other types of casting process usually use machine to complete the casting, and the secondary processing operation is time-consuming and troublesome. The good news is that die casting reduces the need for this kind of operation. In many cases, castings can be shipped immediately after completion of the casting process.
Disadvantages Of Die Casting
On the one hand, compared with other casting processes, die castings are expensive, and the cost of purchase and maintenance of casting machine is very high. Even if relatively cheap zinc is used as casting raw material, the cost is also high. Some defects, such as flow marks, water marks, scratches, dents and so on, may also occur in the die casting.

It is because of the advantages and unique advantages of the die casting parts that the die casting products are now more and more widely used. It plays an important role in many products such as laptop, mobile phone, camera, automobile and motorcycle. Among these products, die casting parts appear in front of consumers as fashionable, environment-friendly, humanized and innovative products, and consumers also highly approve of such products. With the development of die casting technology, die casting parts will certainly be more widely used.
Die casting is great for casting non-ferrous metals. If you can afford the initial tooling cost, it will prove to be very cost-effective in the long run. So, if you need a large-scale die casting solution, then die casting should be enough.
Investment casting should be preferred when you need to cast ferrous metals. There are no viable die casting methods that can cast ferrous metal successfully. So, when you have high-quality requirements and are not concerned about budget, investment casting can be chosen.
Die casting processes are used to make a wide range of products, from cylinder heads and engine blocks to furniture and bicycle frames. Die casting is a general casting process, which has both advantages and disadvantages for manufacturers. Many different metals and alloys are suitable for die casting. Zinc is a common choice for this casting process because of its high ductility and high strength, and it is relatively cheap, so it is very suitable for large-scale manufacturing applications. Other metals that can be used for die casting are aluminum, magnesium, copper, lead, tin and their corresponding alloys.

Die casting process is widely used in the manufacturing sector and automobile industries because of many advantages of the die casting process. Let us have a deep insight into the pros and cons of die casting.
Advantages of die casting :
Because of the use of movable cores, it is possible to obtain complex casting than that by permanent mould casting.
Production rate is very high. The typical rate could be 200 pieces per hour.
Die casting process is completely automated.
Very small thickness can be easily filled because the liquid metal is injected at high pressure.
Very good surface finish in order of 1 micron can be obtained.
The surface generated by the die casting process is directly electroplated without further processing.
Dimensional tolerance is very close in order n between +0.08 to -0.08 can be obtained.
The die has a long life.
Inserts can be readily cast in place.
This process is very economical for large scale production.
It will give better mechanical properties compared to sand casting.
Disadvantages of die casting :
Material limitations all material and alloy can not be cast.
The cost of the machine dies and other equipment is high.
Not economical for small quantity production.
Heavy casting can’t be cast by this process.
Limited to high-fluidity metals.
The air in the die cavity gets trapped inside the casting causes a problem of porosity.
Die casting is one of the most versatile and prolific metal casting processes, characterized by the use of a mold cavity to apply high pressure to the molten metal. The characteristics of die casting process contribute to design die casting parts to meet the requirements of the die casting process.
There are many sources for information on die casting design. These include text books, technical papers, literature, magazines, seminars and courses conducted by engineering societies, trade associations and industry. Often, the die caster selected to produce a component part is an excellent source for information.
To gain maximum advantage of the die casting process, it is always a good idea to draw upon the wide ranging experience of a custom die caster. New designs should be reviewed during the early stage of development. Significant savings may be realized during this interchange of ideas.
Die casting is one of the most versatile and prolific metal casting processes, characterized by the use of a mold cavity to apply high pressure to the molten metal. The characteristics of die casting process contribute to design die casting parts to meet the requirements of the die casting process. Now let’s take a look at the advantages and disadvantages of die casting, and the comparison of parts processed by other manufacturing methods.
ADVANTAGES OF DIE CASTING:
Easy for mass production – Since die casting is made from die casting mold, they can be obtained within specified tolerance and shapes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required. So it’s quiet easy to put on mass production.
Dimensional accuracy and stability – Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant.
Strength and weight – Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.
DISADVANTAGES OF DIE CASTING :
1) All metals and alloys can not be achieved.
2) The cost of machines, dies and other equipment used is high.
3) It’s not cheap to start with small quantity production.
4) Special precautions are necessary for evacuation of air from die cavity, otherwise cause porosity.
5) It’s impossible to get a die casting prototype when product development process.
As you know, die casting is a metal manufacturing process in which molten metal is forced under high pressure into mold tooling cavities. And easily to obtain the desired metal shape, nowadays, it is a widely used in automotive, lighting, industrial, and households.
It is because of the advantages and unique advantages of the above die casting parts that the die casting products are now more and more widely used. It plays an important role in many products such as laptop, mobile phone, camera, automobile and motorcycle. Among these products, die casting parts appear in front of consumers as fashionable, environment-friendly, humanized and innovative products, and consumers also highly approve of such products. With the development of die casting technology, die casting parts will certainly be more widely used.
I agree that using die casting is the way to go. At the company I work at, we recently switched over to using die casting and have seen incredible results. I believe that die casting is for sure the way to go.
The capital cost of foundry equipment and metal molds is high, which often limits the process of mass production. Die castings are relatively simple to manufacture and involve only four major steps, each with a lower incremental cost. It is especially suitable for large quantities of small and medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings have a good surface finish (by casting standard) and dimensional consistency.
